Tv signal broadcasting system

Abstract

Abstract PURPOSE:To broadcast more TV programs in less frequency band by dividing TV signals in field unit and time-compressing every 1 field or plural fields of plural TV programs, composing them in series and transmitting. CONSTITUTION:Time axis of TV signals of TV programs #1-#n inputted to terminals 1-(n) are adjusted respectively by frame synchronizers F.S. 11-n1, and starting time of each field is made uniform, and become synchronized signals. Each TV signal is time compressed by time compressing circuits, and signals #1-#n are applied successively to an adder circuit 10 in time division. Composite signals obtained by the adder circuit 10 are broadcasted through a transmitter 20.
